The Exchequer of Ireland was a body in the Kingdom of Ireland tasked with collecting royal revenue. Modelled on the English Exchequer, it was created in 1210 after King John of England applied English law and legal structure to his Lordship of Ireland. The Exchequer was divided into two parts; the Superior Exchequer, which acted as a court of equity and revenue in a way similar to the English Exchequer of Pleas, and the Inferior Exchequer, which directly collected revenue from those who owed The Crown money, principally rents for Crown lands. The Exchequer primarily worked in a way similar to the English legal system, holding a similar jurisdiction (down to the use of the Writ of Quominus to take over cases from the Irish Court of Chancery). Following the Act of Union 1800, which incorporated Ireland into the United Kingdom, the Exchequer was merged with the English Exchequer in 1817 and ceased to function as an independent body, although the Irish Court of Exchequer, like other Irish courts, remained separate from the English equivalent.
